I worked at a place that had some extremely specialized high-speed printers, which came with print servers that were running OpenServer several years past when that was a reasonable thing to do. I don't know whether it was SCO or the vendor at fault, but these boxes had dozens of unnecessary services on them, including an unpatched copy of the NCSA httpd that was nearly 10 years old. Telnet, finger, chargen, and all those other obsolete services you'd see mentioned in inetd were all enabled by default. I already had a healthy dislike of SCO from their Linux lawsuits from years before, but actually using a SCO product was even worse.
